使用Apache Sqoop从MySQL导入数据-错误:没有用于连接字符串的管理器 [英] Data import from MySQL with Apache Sqoop - Error : No manager for connect string

问题描述

我正在尝试将Mahout与外部数据源集成.我正在关注 Apache Mahout Cookbook 这本书.

I'm trying to integrate Mahout with an External Datasource. I'm following the Apache Mahout Cookbook book for that.

我已经配置了Hadoop 2.4，MySQL服务器，并且已经将一个虚拟数据库导入到mysql中.

I have configured Hadoop 2.4, MySQL server and I have imported a dummy database into mysql.

我还按照本书中的步骤安装了Apache Sqoop，并在Sqoop库(sqoop/lib)中下载并部署了mysql-connector-java-5.1.30.jar

I have also installed Apache Sqoop following the steps in the book and I have downloaded and deployed mysql-connector-java-5.1.30.jar in the Sqoop library (sqoop/lib)

我已经用ant命令构建了sqoop:

I've built sqoop with ant command :

   ant mvn-install

构建正常.

我正在尝试使用本书中所述的以下命令从mysql导入数据:

I'm trying to import data from mysql using the following command as described in the book :

   sqoop import-all-tables --connect jdbc:mysql/localohost/bbdatabank --username root -P --verbose

但是失败，并显示以下错误:

But it's failing with following error :

Warning: /usr/lib/hbase does not exist! HBase imports will fail.
Please set $HBASE_HOME to the root of your HBase installation.
Warning: /usr/lib/hcatalog does not exist! HCatalog jobs will fail.
Please set $HCAT_HOME to the root of your HCatalog installation.

有人可以帮我找到我所缺少的吗?为什么会产生此错误，我该如何解决?

PS::我没有安装HBase或HCatalog，因为这本书说我不需要它.

PS : I haven't installed HBase nor HCatalog cause the book says that I don't need it.

推荐答案

看起来您的jdbc网址不正确，应该像

Looks like your jdbc url is incorrect, it should be like

jdbc:mysql://localhost/bbdatabank
